Evidence-based medicine (EBM) has rapidly developed in recent years and is currently a hotspot in international medicine. The guiding principle behind EBM is that any medical decision should be determined based on objective clinical and scientific evidence, doctor's professional skills and experience, and patient's needs and desires. This paper introduces the concept and practice of EBM and explains how it can be used to solve the issues in stomatology.

Objective To analyze syndrome types and TCM prescriptions of Behcet's disease;To summarize the regularity of TCM syndrome differentiation and treatment principles of Behcet's disease.Methods Related literature in CNKI and VIP database from Jan. 1990 to Oct. 2013 was searched. The syndrome patterns, characteristics of prescriptions and frequency of syndrome were summarized.Results There were 20 syndrome types of Behcet's disease in the 58 collected literature. Damp and hot accumulating poison, spleen and kidney Yang deficiency, liver and kidney Yin deficiency, and hot and damp were common syndromes, occupying 55.4%. Hot and damp occupied 41.3%;Yin deficiency occupied 18.1%;Yang deficiency occupied 12.9%. Liver, spleen and kidney were the main disease locations, occupying 94.4%. There were 197 Chinese herbs in total, and could be classified and further combined into 19 types, among which heat-clearing drugs, tonics, activate blood and removing blood stasis were commonly adopted, occupying 50.6%. There were 66 prescriptions collected, among which 31 were set prescriptions, and 35 were prescriptions formed by self-experience. Longdan Xiegan Decoction and Gancao Xiexin Decoction were commonly adopted.Conclusion Syndrome types and TCM prescription characteristics of Behcet's disease had certain regularity, which can provide reference for clinical diagnosis and treatment.

Objective To understand the gene distribution and drug resistance rate of integron gene of extended spectrumβ‐lac‐tamases(ESBLs) producing Klebsiella pneumonia infection in ICU elderly patients in order to provide the basis for rational use of antimicrobial agents .Methods The BioMerieux VITEK‐2 Automated Microbes Identification System was adopted to conduct the bacteria identification and drug susceptibility test on various clinical specimens of ICU elderly patients in our hospital from January 2013 to December 2015 .The integron gene in 167 strains of ESBLs‐producing Klebsiella pneumoniae was analyzed by PCR ,and the gene was identified by sequencing .Results Among 386 strains of Klebsiella pneumoniae ,the detection rate of ESBLs‐producing strains was 43 .26% ;the positive rate of integron was 50 .89% ,the detected integron was class Ⅰ integron;aadA2 ,aadA1 ,aada16 , dfra27 and arr‐3 genes were amplified from integron variable region;the drug resistance rate of ESBLs‐producing integron gene pos‐itive strains was significantly higher than that of integron gene negative strains .Conclusion the ICU elderly patients with ESBLs‐producing Klebsiella pneumoniae infection is closely related to the integron gene and integron plays an important role in bacterial drug resistance .

Idiopathic scoliosis is one of common adolescent malformations,it will harm patient's physical and mental health seriously.These years,surgical technique of adolescent idiopathic scoliosis has developed from rectification of single plane and segment to multi planes and segments,the effect of rectification improved much at the same time.This article reviews the developed course of the surgical technique of adolescent idiopathic scoliosis from two aspects:operating approach and operating method.It also recommends the extensively used operating styles at present.

Objective To analyze the transformation of the function of research management department in medical institutions based on the knowledge management.Methods The value chain is introduced to portray the functions of research management department, and a survey is employed to collect existing problems in research management.Results Lack of knowledge management is main reason that limits the research development in medical institutions.Conclusions It is very important to re define the strategy for conducting the research in the medical institutions and to improve the knowledge management in those medical institutions.

The risk factors of Clostridium difficile infections increased in recent years , such as the underlying disease, hospitalization duration, age, the use of antibiotics, the use of proton pump inhibitors and so on.The rate of Clostridium difficile infection and recurrence are still high despite the appear of new antibiotics such as rifaximin, nitazoxanide, tigecycline, ramoplanin, fidaxomicin, and non-antimicrobial such as drugs toxin neutralizer chamber , biological therapeutic agents , fecal transplantation , systemic antibody method , intravenous immunoglobulin and so on.The vaccine is the most ideal way of prevention and treatment of Clostridium difficile infection.The research in Clostridium difficile vaccine lasted for nearly 20 years.Except the monoclonal antibody vaccine and toxoid vaccine against toxin A and toxin B have achieved better results in the human , some recombinant vaccines against the toxin receptor and the key pathogenic factor of Clostridium difficile also achieved good effect in animal.

Objective To study some risk factors of acquired nosocomial pneumonia in tumor case nosocomial infection.Methods 77 tumor case with nosocomial infection were chosen as cases from the patients in hospital for 1:1 case control study.Results It was found that the fatality rate of acquired NP in tumor pattens was 14 3%.Some risk factors of acquired nosocomial infection in tumor case remained significant through logistic regression analysis showed,such as state of an immunosuppression therapy; operation,hospitalization duration,antibiotics application time and mechanical ventilation.Conclusions It was suggested that the iatrogenic pneumonia is comes from multiple risk factors and it should be paid attention. This is the most important step to control nosocomial infection of tumor case in the hospital happen.
